Compatibility: SRAM / Shimano mid or long cage derailleur, or with 22mm RD link for short cage derailleur
Wide ratio cassette to extend your shifting performance
For Shimano HG splined freehubs, not compatible with Sram XD Driver
（Sunrace since 1972）
If your rear derailleur is short cage or can’t release the large cog, you either can adjust the long B-Screw or just mount the RD extender link with the product, the 22mm extension add-on. It could fix the compatibility issue.
Package Includes :
1 X New Sunrace CSMX3 10 speed cassette in Silver 11-42T without retail packaging
